Shock & Impact

Sound Blocking & Absorption

As airlines and railways look to improve the customer experience, unique materials are available to support new design techniques for reducing noise levels. Cellular silicone foams have excellent memory, making them a long-term solution to reducing vibration-induced noise in interiors. BISCO® Silicones reduce vibration and are designed to meet stringent standards for extreme temperatures and flames – A2 Sound Barrier, HT-200 Sound block, and MF1™ Bun Silicones.

Durability

Silicone-based polymers maintain physical properties over a wide temperature range (temperature stability) and have great environmental resistance, specifically, very low water absorption. BISCO® HT-200 sound block materials are specifically designed to reduce the transmission of sound within the interior spaces while inhibiting the spread of fire and smoke.

True absorption and dissipation are provided by materials that are porous to “capture” sound pressure wave energy as it bounces around inside a cell and eventually loses its mechanical energy to penetrate. BISCO® materials have a unique open cell structure that produces a breathable foam that will not break down with continual use.
